Agreed on that. I just thought it could be wise parse natively what is already out there. Anyways adapt our DocBlock annotation parsers to parse both (native PHP annotations and docblocks) shouldn't be that hard either. As far as I see annotations are supposed to be accessed through reflections right? Or will it do something automatically as in Python? Cheers, > > Thanks.
